In this method, a water-soluble slurry of finely ground gold ore is treated with an alkali cyanide to form a water-soluble gold cyanide complex. This leaves finely ground ninetails or gangue in suspension. These tailings or slimes are typically removed by thickening with organic flocculants. Another method is to thicken the finely ground gold ore and gangue with a flocculant and then add cyanide so that the gold is complexed and solubilized and can be purified.
